Junko Enoshima

As a young fashionista, Junko is described as simply "not fake", charismatic and eager to try new things. During her first appearances, she comes across slightly air-headed and hot-tempered. In the official artbook, she is described as a person who "drips with dissatisfaction the moment she opens her mouth" and tends to be in trouble with her classmates. She is also mentioned to be a bit too talkative with an overly carefree attitude.

Junko is shown to be easily bored, her mannerisms and behavior tending to be slightly erratic and unstable: she has many different personas, and keeping one up for too long bores her before she quickly and seamlessly changes to another one, with her voice changing as well: her "haughty superiority" makes her act like a stereotypical British monarch, her "sickening cuteness" makes her act like a moe, her "clinical sophistication" makes her act more maturely like a teacher, her "severe depression" makes her act depressed to the point of being on the verge of crying, her "eerie stoicism" makes her act in a monotone style and her "boisterous vulgarity" makes her like a stereotypical rockstar. Sometimes, she talks as if narrating a story, writing her thoughts down in a notebook.

Contrasting with this, Junko maintains a more upbeat "valley-girl" style persona, such interjecting "like" and "totally" into her sentences and speaking in a more haughty demeanor. She's friendly, albeit pushy, and even claimed Makoto Naegi is an "omega male" due to his passive nature when she spent time with him. She is also capable of feeling actual love to those she is close with.
